I'm getting a lot closer to being ready to paint my duster. I will be useing a base coat clear coat. This is my first attempt at painting a whole car a different color. How do I get the door jambs and all them places painted without leaveing lines.If I mask off I'm worried about leaving lines that are visable. Do you have to feather sand the edges after you remove the masking to mount the doors so you can paint the outside. I'm just trying to visualize how the parting lines would flow out. Ive seen cars with all the jambs and stuff painted and then assembled befor the outside gets sprayed but I just don't know how it blends in in those areas.
